Filed:

Dec 16, 2002

Appl. No.:

10/498442

Inventors:

Jennifer Keane White - Brookline MA, US
James Sidney Titus - Sharon MA, US

Assignee:

The General Hospital Corporation - Boston MA

International Classification:

A61M 29/00

US Classification:

606191

Abstract:

A perfusion cannula constructed of a wire mesh or other structure having an expandable portion capable of expanding from a constricted state to an expanded state such that a vessel is stented open while permitting fluid flow through a cannula into the vessel.

Appl. No.:

13/398277

Inventors:

James Sidney Titus - Sharon MA, US

International Classification:

A61B 1/018
A61B 1/07

US Classification:

600153, 600178

Abstract:

An optical coupler is disclosed with an attachment section for mounting at a distal end of an optical imaging device for visualizing a surface area covered with an opaque fluid and/or particulate matter. The coupler includes a visualization section at one end of the coupler that includes a proximal surface for engaging the distal end of the optical imaging device, an attachment section connected to and extending away from the visualization section, an outer surface spaced apart from the proximal surface, and may include a hollow instrument channel extending from the proximal surface toward the outer surface. This surface extends continuously from a first outer side boundary across to a second opposite outer side boundary of the visualization section. The visualization section can be formed from an elastic material capable of transmitting an optical image of the surface area. In one form, the material is a silicone gel or elastomer.

Abstract:

An optical coupler is disclosed for mounting at a distal end of an optical imaging device for visualizing a surface area covered with an opaque fluid and/or particulate matter. The coupler includes a visualization section at one end of the coupler and an attachment section connected to and extending away from the visualization section. The attachment section is dimensioned to be mounted at the distal end of the optical imaging device. The visualization section includes a proximal surface for engaging the distal end of the optical imaging device. The visualization section includes an outer surface spaced apart from the proximal surface. The outer surface extends continuously from a first outer side boundary across to a second opposite outer side boundary of the visualization section. The visualization section may include one or more supporting elements extending laterally away from the visualization section for facilitating passage of the optical coupler through an object, such as a body lumen.
